Generally, ultrasonic flaw detection is usually used for seamless steel pipes to detect defects on the steel pipes. There are two types of ultrasonic testing: direct contact method and water immersion method. The direct contact method requires grinding the ultrasonic probe to make the contact surface of the probe have the same curvature as the outer diameter of the steel pipe to be tested. In the ultrasonic water immersion test method, there is a water layer of a certain thickness between the surface of the steel pipe to be tested and the probe, and the probe does not directly contact the surface of the steel pipe.
